Case Overview
The Parties
⚖️ Plaintiff
Non-practicing entity (NPE) asserting a patent portfolio in advanced wireless communications technology, d/b/a Vivato Technologies.
🛡️ Defendant
Major telecommunications provider deploying 4G LTE and 5G wireless infrastructure, co-defendant with Verizon and T-Mobile.
Patents at Issue
This landmark case involved five U.S. patents covering foundational techniques in spatially directed wireless transmission, beamforming coordination, and multipath signal management—technologies embedded in modern 4G and 5G network infrastructure. These patents are registered with the U.S. Patent and Trademark Office (USPTO).
- • US7,177,369 B2 — Directed MIMO communications
- • US8,737,511 B2 — Directed wireless communication
- • US8,289,939 B2 — Multipath communication methods and apparatuses
- • US10,594,376 B2 — Signal communication coordination
- • US10,715,235 B2 — Signal communication coordination (continuation)

The Verdict & Legal Analysis
Outcome
On January 8, 2026, Judge J. Rodney Gilstrap’s court granted the Joint Motion to Dismiss (Dkt. No. 299). The order provided that all claims by XR Communications against all defendants were **dismissed WITH prejudice**, and all counterclaims by defendants against XR Communications were **dismissed WITHOUT prejudice**. No damages figure was publicly disclosed, strongly indicating a confidential settlement agreement.
Key Legal Issues
The resolution of this case through a dismissal “with prejudice” for plaintiff’s claims, while defendants’ counterclaims were dismissed “without prejudice,” offers a legally significant insight into settlement dynamics. This structure suggests a comprehensive resolution for the asserted claims against these defendants, while preserving defendants’ ability to reassert invalidity challenges if the patents were to be litigated again. This type of resolution reinforces several patterns in NPE patent assertion against major wireless carriers, including the importance of portfolio breadth and multi-defendant coordination, particularly in venues like the Eastern District of Texas.
